Carotids' layout and variety of posts make it a little hard to know what to expect behind each link, but the author usually choses stories and sites that are worth a look. I was entertained. And informed! Now I can say I've seen what a mad cow looks like (note: the cow is actually suffering from foot-and-mouth disease). And the author linked to this fascinating thread on pulseless hearts, which our neighborhood of the blogosphere completely missed.
